On Saturday, Wilde shared a video in support of presidential candidate Hillary Clinton and revealed she was expecting a girl.

“As someone who is about to have a daughter, this hits me deep in my core,” she tweeted.

Having a big family is something Wilde has wanted even before confirming her second pregnancy.

“I’m desperate for more [kids]!” she told PEOPLE in April, just before announcing she was expecting another baby. “I love my siblings so much and Jason has incredible siblings, too. The more the merrier.”
